Active chassis - Four C*
Active chassis "Four-C" (Continously Controlled
Chassis Concept), regulates the characteristics
of the shock absorbers so that the car's driving
characteristics can be adjusted. There are three
settings: Comfort, Sport and Advanced.
Comfort
This setting means that the car is perceived as
being more comfortable on rough and uneven
road surfaces. Shock absorption is soft and the
movement of the body is smooth and gentle.
Sport
This setting means that the car is perceived as
being more sporty and is recommended for more
active driving. Steering response is faster than in
the Comfort mode. Shock absorption is harder
and the body follows the road in order to reduce
rolling during cornering.
Advanced
This setting is only recommended on very even
and smooth road surfaces.
The shock absorbers are optimised for maximum
roadholding and rolling in bends is further mini-
mised.
Operation
Control buttons.
The required chassis setting is selected using the
centre console buttons. The setting used when
the engine was switched off is re-activated when
the engine is next started.
Adjustable steering force*
Speed related power steering causes the steer-
ing wheel force to increase with the speed of the
car in order to give the driver enhanced sensitiv-
ity.
On motorways the steering feels firmer. Steering
is light and requires no extra effort when parking
and at low speed.
The driver can choose between three different
levels of steering force for road responsiveness
or steering sensitivity in the menu system MY
CAR (p. 117):
•
Once there, search for
Steering force level
and select Low, Medium or High.
This setting is not accessible when the car is
moving.
NOTE
In certain situations the power steering may
become too hot and then needs to be tempo-
rarily cooled - during this time the power
steering operates with reduced power and
turning the steering wheel may then be per-
ceived to be slightly heavier.
In parallel with the temporarily reduced steer-
ing assistance the combined instrument panel
shows a message.
